Setup and Assembly
Any missing parts or damage should be reported
immediately to your JET
®
distributor. Do not use a
damaged tool. Read this instruction manual
thoroughly for operation, maintenance and safety
instructions.

Operation
The pneumatic shear must be
properly lubricated before operation. See
“Lubrication” section.
Figure 1
1. Remove protective cap from air inlet (Figure
1). If an in-line oiler is not being used, add 4
or 5 drops of air tool oil (not included) into the
air inlet.
2. Blow out air line to remove any dirt or
moisture, then connect air supply hose to
tool. Set air pressure to 90 psi.
IMPORTANT: Connecting a quick-change
coupling directly to the tool is not
recommended, as vibration may cause the
connection to fail. Instead, add a leader hose
and install any quick-change couplings
farther down the line.
3. Place cutting blades against workpiece, and
both hands on tool.
4. Press trigger to operate. Speed is regulated
by pressure applied to trigger.
5. Use moderate pressure against workpiece;
do not force tool.
6. Release trigger to stop tool.
Adjustment
Disconnect shear from air
supply before making any adjustments.
Head position
1. To swivel head, loosen (do not remove) the
three socket head screws with a hex wrench,
just enough to allow head to swivel.
2. Rotate head to desired angle, and retighten
the three screws.
Maintenance
Lubrication
The shear should be lubricated daily (or before
each use) with air tool oil through the air inlet.
During continual operation, it should be re-oiled
every 1 to 2 hours. This can be done with an in-
line oiler, or manually. If done manually, proceed
as follows:
1. Disconnect air hose from tool.
2. Place 4 or 5 drops of air tool oil into air inlet.
NOTE: Air tool oil not provided; it is available
at most major hardware and tool stores. SAE
#10 oil or sewing machine oil may be used
as a substitute. Do not use detergent oil.
3. Re-connect air. Run shear at low throttle
without load for a few seconds to distribute
the oil throughout tool.
4. When finished operating shear, disconnect
air hose. Wipe off housing with a dry cloth.
Place 4 or 5 drops of air tool oil into air inlet;
re-connect air and run tool for a few seconds
to distribute the oil. Disconnect air.
Storage
Avoid storing the shear in very humid locations
which promotes rusting of internal mechanisms.
Always oil the tool and disconnect air hose before
storage.
